Each of these -masters can use 8 (RTL9300) or 16 (RTL9310) different pins for SDA. -This multiplexer directly controls the two masters and their shared -IO configuration registers to allow multiplexing between any of these -busses. The two masters cannot be used in parallel as the multiplex -is protected by a standard multiplex lock. - -Submitted-by: Birger Koblitz <git@birger-koblitz.de> ---- - drivers/i2c/muxes/Kconfig | 9 +++++++ - drivers/i2c/muxes/Makefile | 1 + - 2 files changed, 10 insertions(+) - ---- a/drivers/i2c/muxes/Kconfig -+++ b/drivers/i2c/muxes/Kconfig -@@ -99,6 +99,15 @@ config I2C_MUX_REG - This driver can also be built as a module.
